■The meaning of each symbol in this manual and on your equipment is as follows.
This is the safety alert symbol.
Read and follow instructions carefully to avoid dangerous situation.
This symbol alerts the user to the presence of “dangerous voltage”
inside the product that might cause harm or electric shock.
■After reading this manual, keep it in the place that the user always can contact
easily.
■This manual should be given to the person who actually uses the products and is
responsible for their maintenance.

ii
WARNING
Do not remove the cover while power is applied or the unit is in operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.
Otherwise, you may get an electric shock due to high voltage terminals or charged capacitor
exposure.
Do not remove the cover except for periodic inspections or wiring, even if
the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10 minutes
after disconnecting the input power and after checking the DC link voltage is
discharged with a meter (below DC 30V).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or
pinching.
Otherwise, you may get an electric shock.

iii
CAUTION
Install the inverter on a non-flammable surface. Do not place flammable
material nearby.
Otherwise, fire could occur.
Disconnect the input power if the inverter gets damaged.
Otherwise, it could result in a secondary accident and fire.
Do not touch the inverter while the input power is applied or after removed. It
will remain hot for a couple of minutes.
Otherwise, you may get bodily injuries such as skin-burn or damage.
Do not apply power to a damaged inverter or to an inverter with parts
missing even if the installation is complete.
Otherwise, electric shock could occur.
Do not allow lint, paper, wood chips, dust, metallic chips or other foreign
matter into the drive.
Otherwise, fire or accident could occur.
OPERATING PRECAUTIONS
(1) Handling and installation
Handle according to the weight of the product.
Do not stack the inverter boxes higher than the number recommended.
Install according to instructions specified in this manual.
Do not open the cover during delivery.
Do not place heavy items on the inverter.
Check the inverter mounting orientation is correct.
Do not drop the inverter, or subject it to impact.
Use the ground impedance of 100ohm or less for 200 V Class and 10ohm or less for 400V class.
Take protective measures against ESD (Electrostatic Discharge) before touching the PCB for
inspection or installation.
Use the inverter under the following environmental conditions:

iv
Ambient temp.
CT Load: - 10 ~ 50℃(non-freezing)
VT Load: -10 ~ 40℃(non-freezing)
Note: Use below 80% of load when used under VT
Load at 50℃
Relative humidity 90% RH or less (non-condensing)
Storage temp. - 20 ~ 65 ℃
Location Protected from corrosive gas, combustible gas, oil
mist or dust
Altitude, Vibration Max. 1,000m above sea level, Max. 5.9m/sec2
(0.6G) or less
Environment
Atmospheric pressure 70 ~ 106 kPa
(2) Wiring
Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to the output of
the inverter.
The connection orientation of the output cables U, V, W to the motor will affect the direction of
rotation of the motor.
Incorrect terminal wiring could result in the equipment damage.
Reversing connection of the input/output terminals(R,S,T / U,V,W) could damage the inverter.
Only authorized personnel familiar with LS inverter should perform wiring and inspections.
Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily
injury.
(3) Trial run
Check all parameters during operation. Changing parameter values might be required depending
on the load.
Always apply permissible range of voltage to the each terminal as indicated in this manual.
Otherwise, it could lead to inverter damage.
(4) Operation precautions
When the Auto restart function is selected, stay away from the equipment as a motor will restart
suddenly after an alarm stop.
The Stop key on the keypad is valid only when the appropriate function setting has been made.
Prepare an emergency stop switch separately.
If an alarm reset is made with the reference signal present, a sudden start will occur. Check that
the reference signal is turned off in advance. Otherwise an accident could occur.
Do not modify or alter anything inside the inverter.
Motor might not be protected by electronic thermal function of inverter.
Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.
Use a noise filter to reduce the effect of electromagnetic interference. Otherwise nearby electronic
equipment may be affected.
In case of input voltage unbalance, install AC reactor. Power Factor capacitors and generators may
become overheated and damaged due to potential high frequency noise transmitted from inverter.

v
Use an insulation-rectified motor or take measures to suppress the micro surge voltage when
driving 400V class motor with inverter. A micro surge voltage attributable to wiring constant is
generated at motor terminals, and may deteriorate insulation and damage motor.
Before operating unit and prior to user programming, reset user parameters to default settings.
Inverter can easily be set to high-speed operations, Verify capability of motor or machinery prior to
operating unit.
Stopping torque is not produced when using the DC-Break function. Install separate equipment
when stopping torque is needed.
(5) Fault prevention precautions
Provide a safety backup such as an emergency brake which will prevent the machine and
equipment from hazardous conditions if the inverter fails.
(6) Maintenance, inspection and parts replacement
Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.
Refer to Chapter 12 for periodic inspection (parts replacement).
(7) Disposal
Handle the inverter as an industrial waste when disposing of it.
(8) General instructions
Many of the diagrams and drawings in this instruction manual show the inverter without a circuit
breaker, a cover or partially open. Never run the inverter like this. Always place the cover with
circuit breakers and follow this instruction manual when operating the inverter.
